Method for washing a cavity in a microfluidic component and a microfluidic component for carrying out the method. The invention relates to a method for washing at least one cavity (20') in a microfluidic component, wherein, in the cavity (20'), a first liquid (F1) is present and at least one second liquid (F2) is supplied to the cavity (20') for washing. According to the invention, an air bubble (L) is fed to the cavity (20') before supply of the washing liquid (F2). The air bubble (L) which virtually acts as a barrier layer between the first liquid (F1) and the following washing liquid (F2), makes possible a notable increase in washing efficiency. Overall, this method leads to a saving in washing liquid (F2) and washing time. In addition, a microfluidic component is proposed for carrying out the method.

A device and a method for actuating a carpule are proposed, wherein a piston in the carpule is moved by means of a ram that is telescopically extensible by rotation and, in this way, a liquid medicament formulation is dispensed. To perform different procedures, different operating movements are provided, in particular the operation of an operating element in opposite directions and/or the operation of different operating elements. This facilitates simple, intuitive and safe operation.
